The San Bernardino County Special Districts Department (SDD) began working with the IERCD in 2009, collaborating on application for grant monies from the Habitat Conservation Fund for use at the then 1,200-A North Etiwanda Preserve (NEP). The NEP is a contiguous conserved area north of the City of Rancho Cucamonga, set aside as mitigation for impacts related to the extension of the 210 freeway. Since its dedication as a conserved space, the NEP has grown to over 1,700-A and boasts a series of educational signs and trails, leading visitors passively over its grounds while featuring key vegetation communities, wildlife, and vestiges of water conveyance systems and previous indigenous and early settler populations the site once housed. Other key NEP partners include the San Manuel Band of Mission Indians and the California Department of Fish and Wildlife.
In 2010, the IERCD and SDD began facilitation of annual educational field trips to the Preserve for grades 2-12, focusing on NEP-centric topics including fire, water conservation, and sensitive, threatened, and endangered species. The trips are continuing in the current academic year, and details for booking, what to expect, and a list of state and federal educational standards corresponding to trip content can be viewed on the SDD and IERCD websites. All trips are free, including busing.
